Sync your Global Address List Automatically to Mobiles

Use our DidItBetter Software sync apps to easily and automatically sync your Exchange Global Address List (GAL) or Office 365 GAL to Outlook personal contact folders for a copy of your corporate address book contacts, for viewing on mobiles (iPhones, Androids, Exchange-enabled mobiles), and for business caller ID recognition. Mobile devices natively sync with your Outlook Contacts mailbox folder, however most have a limitation of not being able to automatically sync contacts from the Office 365/Exchange Global Address List or from a corporate address book/contact list maintained in a public folder, for example. Even if possible, many accounts would need to be hidden to limit users from viewing or accessing certain service accounts or distribution lists.

With our Add2Exchange GAL sync app, you can automatically synchronize your global address list to selected local Contact folders. Global Address List synchronization allows you to treat the Exchange GAL or Office 365 GAL as the source folder to be synchronized one way with selected destination (target) folders i.e. your users’ local Outlook Contact folders. Once the GAL contacts are in the personal contact folder, the mobile device’s sync software (Exchange ActiveSync) takes over syncing it down to your mobiles.

Common GAL Sync Uses

  • Enterprise Mobility. Easily access your corporate GAL contacts on your iPhones, Androids, and smartphones. Whether your company uses on premise Exchange or Office 365, you can automatically sync your GAL contacts to Outlook mailboxes and Exchange enabled mobile devices.
  • Updated Contacts Anywhere Anytime. Easily maintain and access up to date company contacts. Once installed and set up, synchronization is automatic based on the sync process interval and settings selected. Additions, changes, and deletions are now handled automatically.
  • Caller ID Recognition of Company Contacts. You can easily identify who’s calling you from the office, instead of answering an unrecognized number that turns out to be another robocall or unsolicited telemarketer.
  • Text Messaging Identification. When a coworker or business associate needs to reach you via texting, instead of seeing a phone number in the text message, you can easily identify who’s texting you from work.
  • Photo Display. If photos are your thing, you can even include and sync profile photos so your employees can see who’s calling from the office.
  • Cross Tenant Collaboration. When you need to share GAL contacts between two organizations.
  • Mergers and Acquisitions. When you need to consolidate the GAL contacts between two different companies.

Key Features

  • Automatic GAL synchronization. Automatic synchronization of your global address book to your users’ local Contact folders and mobiles (iPhones, Androids, Exchange-enabled devices). Create one way ‘source to destination’ relationship templates for faster deployment to selected users within a distribution group.
  • GAL exclusions supported. Any account or distribution list may be included or excluded from the sync. Just ‘point and click’ to select which users to sync the contacts to. Include or exclude new users added to the GAL, or even include Outside contacts to sync to all users.
  • Support for caller ID and AD photos. Active Directory Pictures can be automatically synced so when the contact calls, the caller’s picture appears on the phone! Your team can easily identify who’s calling from the office.
  • Sync to all or some users. Some organizations want to sync the GAL to all users in the organization, while others may not wish to sync the global address list contacts to everyone. You decide which users to sync the GAL company contacts to for access and viewing.
  • Distribute and share all address book fields, or select conditional syncing for certain fields. All fields are set by default to be included in the sync including postal addresses, phone numbers, date fields, and more. You can use the conditional syncing features to limit which fields to sync.
  • Incremental updates for faster synchronization. After the initial sync, only additions and changes are synchronized increasing sync speed time.
  • Advanced GAL synchronization options. Change the email display name format for synchronized contacts to a variety of different formats including first name last name, first initial last initial, alias, display name, SMTP Address and much more. Include Distribution List members, to your Global Address List sync, as well as inclusion of email enabled folders.

We were looking for an affordable solution to sync our global address list contacts to our iPhones and Androids. After doing some research for an Exchange server-side solution to our problem, we chose DidItBetter’s Add2Exchange Enterprise solution with the GAL Sync Manager. All other solutions only addressed part the problem, were device specific, or wanted to charge us an arm and a leg … Add2Exchange Enterprise is running completely transparent to our users, offering a complete end-to-end solution with no user intervention required. There are no client plug-ins or mobile apps needed, and our employees don’t have to do anything to make it happen. We had the DidItBetter Software support team install it and train us on best practices with the software .. very responsive and professional.

We needed an Office 365 solution. When we had on premises Exchange, we used Add2Exchange to sync our global address list to our users’ mobiles and didn’t realize how heavily we relied on it until we moved to Office 365. When we migrated, we contacted DidItBetter to see if they had another sync tool we could use and they came through for us once again with Add2Outlook Server. Their support team was very helpful (and patient with us) with the transition from Add2Exchange Enterprise to Add2Outlook and developed a nifty conversion program to avoid duplication and dereplication.
